Princess Diana feared Prince Charles was trying to kill her so he could marry their sons' nanny, Tiggy Legge-Bourke, according to a handwritten letter admitted into evidence in the ongoing inquest into her death. "My husband is planning 'an accident' in my car, brake failure and serious head injury in order to make the path clear for him to marry Tiggy," the letter says.

The letter was sent to Di's then-butler Paul Burrell less than a year after she separated from Charles. "I still don't believe in it," said one the Diana's closest confidantes. "Paul Burrell was perfectly capable of imitating Princess Diana's handwriting." The inquest was prompted by Mohamed Al-Fayed's accusations that British agents killed Diana and her boyfriend, Fayed's son Dodi, to prevent their marriage.
